Global spending on cloud infrastructure services increased 35 percent in the third quarter of 2021 to reach US$49.4 billion for the quarter, and implying full-year revenue for cloud infrastructure service providers in the range of $185 billion or so.
Canalys defines cloud infrastructure services as those that “provide infrastructure as a service and platform as a service, either on dedicated hosted private infrastructure or shared infrastructure.”
One source of possible definitional difference is how to count “application as a service” revenue, particularly important when evaluating Microsoft, Oracle or IBM figures, for example.
Canalys says it excludes the value of “software as a service”, but includes revenue generated from the infrastructure services being consumed to host and operate them.
Other analyses tend to confirm the Canalys market share figures, which rank Amazon Web Services with 32 percent market share; Microsoft Azure at 21 percent and Google Cloud at eight percent share.
